Case reports: arsenic pollution in Thailand, Bangladesh ...

Arsenic water levels to 9,000 pg/L were reported; such levels are substantially above any guideline levels. A long-term plan to mitigate arsenic contamination was devised in 1998-2000. The plan involved removal of arsenic-contaminated land and improved management of mining wastes. However, at $22 million, the cost was deemed prohibitive for the ...

Origin of arsenic in Bangladesh groundwater

Twenty years ago, Smith and colleagues described groundwater arsenic (As) contamination in Bangladesh as the "largest mass poisoning of a population in history." An estimated 60 million people were unknowingly drinking groundwater containing dangerous concentrations of naturally occurring As.
